Distinct features of C/N balance regulation in Prochlorococcus sp. strain MIT9313
Domínguez-Martín, María A.; López-Lozano, Antonio; Rangel Zúñiga, Oriol Alberto; Díez, Jesús; García-Fernández, José Manuel (Oxford University Press, 2018)The abundance and significant contribution to global primary production of the marine cyanobacterium Prochlorococcus have made it one of the main models in marine ecology. Several conditions known to cause strong effects ... -
Glucose Uptake and Its Effect on Gene Expression in Prochlorococcus
Gómez-Baena, Guadalupe; López-Lozano, Antonio; Gil-Martínez, Jorge; Lucena, José Manuel; Díez Dapena, Jesús; Candau, Pedro; García-Fernández, José Manuel (Public Library Of Science (PLOS), 2008)The marine cyanobacteria Prochlorococcus have been considered photoautotrophic microorganisms, although the utilization of exogenous sugars has never been specifically addressed in them. We studied glucose uptake in ... -
Glutamine Synthetase Sensitivity to Oxidative Modification during Nutrient Starvation in Prochlorococcus marinus PCC 9511
Gómez-Baena, Guadalupe; Domínguez-Martín, María A.; Donaldson, Robert P.; García-Fernández, José Manuel; Díez Dapena, Jesús (Public Library of Science, 2015)Glutamine synthetase plays a key role in nitrogen metabolism, thus the fine regulation of this enzyme in Prochlorococcus, which is especially important in the oligotrophic oceans where this marine cyanobacterium thrives. ... -
Marine Synechococcus sp. Strain WH7803 Shows Specific Adaptative Responses to Assimilate Nanomolar Concentrations of Nitrate
Domínguez-Martín, María A.; López-Lozano, Antonio; Melero-Rubio, Yesica; Gómez-Baena, Guadalupe; Jiménez-Estrada, Juan Andrés; Kukil, Kateryna; Díez, Jesús; García-Fernández, José Manuel (American Society for Microbiology, 2022)Marine Synechococcus, together with Prochlorococcus, contribute to a significant proportion of the primary production on Earth. The spatial distribution of these two groups of marine picocyanobacteria depends on different ... -
Nitrogen starvation induces extensive changes in the redox proteome of Prochlorococcus sp. strain SS120
McDonagh, B.; Domínguez-Martín, María A.; Gómez-Baena, Guadalupe; López-Lozano, Antonio; Díez, Jesús; Bárcena Ruiz, José Antonio; García-Fernández, José Manuel (Wiley, 2012)Very low nitrogen concentration is a critical limitation in the oligotrophic oceans inhabited by the cyanobacterium Prochlorococccus, one of the main primary producers on Earth. It is well known that nitrogen starvation ... -
Physiological Regulation of Isocitrate Dehydrogenase and the Role of 2-Oxoglutarate in Prochlorococcus sp. Strain PCC 9511
Domínguez-Martín, María A.; López-Lozano, Antonio; Díez Dapena, Jesús; Gómez-Baena, Guadalupe; Rangel Zúñiga, Oriol Alberto; García-Fernández, José Manuel (Public Library of Science, 2014)The enzyme isocitrate dehydrogenase (ICDH; EC 1.1.1.42) catalyzes the oxidative decarboxylation of isocitrate, to produce 2- oxoglutarate. The incompleteness of the tricarboxylic acids cycle in marine cyanobacteria confers ... -
Physiological Studies of Glutamine Synthetases I and III from Synechococcus sp. WH7803 Reveal Differential Regulation
Dominguez Martin, Maria Agustina; Díez, Jesús; García-Fernández, José Manuel (Frontiers, 2016)The marine picocyanobacterium Synechococcus sp. WH7803 possesses two glutamine synthetases (GSs; EC 6.3.1.2), GSI encoded by glnA and GSIII encoded by glnN. This is the first work addressing the physiological regulation ... -
Proyecto Europeo: TRANSUCYNA E -Proyecto FP7-PIOF-GA-2013-625188-TRANSUCYNA

Regulatory and metabolic adaptations in the nitrogen assimilation of marine picocyanobacteria
Díez, Jesús; López-Lozano, Antonio; Domínguez-Martín, María A.; Gómez-Baena, Guadalupe; Muñoz Marín, Mª Carmen; Melero-Rubio, Yesica; García-Fernández, José Manuel (Oxford University Press, 2022)Prochlorococcus and Synechococcus are the two most abundant photosynthetic organisms on Earth, with a strong influence on the biogeochemical carbon and nitrogen cycles. Early reports demonstrated the streamlining of ...
